There is a scratch on my digital camera lenses, any way to repair it without replacing len?

If it's an expensive lens, I'd take it to a camera store and ask their opinion. While I've never had it done, I think I've heard that lens elements can be replaced. But I'd expect it to be an expensive repair!

If it's only a tiny scratch, it may not seriously affect your photos. But if you're asking this question, the scratch must be causing problems with your shots.

sorry, i dont think so

Like Greg says, check your actual images and see if the scratch is showing up in your photos before you freak out about it. Sometimes you can get away with a scratched lens.
